We place rings of the most common ring sizes inside our candles. Most often the rings are sizes 6-8.
We unfortunately do not have the option to specify what size ring you want inside your candle.
If someone has a ring inside their candle that is either too big or too small then they most often will give out away to a friend or family member.
If the ring is worth $100+ then most people don't mind spending a few dollars with a local jeweler to get the ring sized to their finger. After all the ring is a bonus that comes with the candle!
